In a small and cold town in Norway, the snowplow driver Nils Dickman is selected by the residents to be awarded with the title of "The Citizen of the Year". When his son Ingvar Dickman is found dead by overdose, the police do not care and do not believe in Nils that says that Ingvar was not dug addicted. Soon Ingvar's friend Finn Heimdahl looks for Nils and tells that his son was wrongly murdered by drug dealers that Finn had lured. The vigilante Nill kills the drug-dealers one by one, and their boss, Ole 'Greven' Forsby, believes the Serbian drug dealers are behind the murderers, disputing territory despite their deal. He orders to kill a Serbian dealer, who is the son of a powerful drug lord, initiating a war between the gangs. But Nils is not satisfied and still seeks revenge against Forsby.—Claudio Carvalho, Rio de Janeiro, Brazil
